TABLE-LEAF SUPPORT.

, SPECIFICATION forming part of Letters Patent No. 318,773, dated May26,1885.

Application filed February 24, 1885. (No model.)

To all whom it may concern:

Be it known that I, CHARLES E. McGLINoH- EY, of Cleveland, in the countyof Cuya' hoga and State of Ohio, have invented certain new and usefulImprovements in Table-Leaf Supports; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it pertains tomake and use the same.

My invention relates to improvements in table-leaf supports,having forits object a laterally-swinging arm or bracket with a screwcam on thebracket-support to engage and elevate the bracket as the latter isturned to support the tableleaf, t0 the end that the tableleaf mayalways be supported in a horizontal position, and any wear of the partsis taken up by swinging the arm a trifle farther under the table-leaf.

With this object in view my invention consists in certain features ofconstruction and in combination of parts hereinafter described, andpointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation showing myimproved device in position supporting a sewing-machine table-leaf. Fig.2 is a side elevation of the ta ble-leaf-supporting arm detached fromits bearings. Fig. 3 is a view in perspective of the socket device forthe arm-support. Fig. 4 is a view in perspective of a modified form ofthe arm-support.

A represents the table; B, the table-leaf; C, the supporting-arm for thetable-leaf, and D the socket or support for the arm. The partD hasaflange or flat part, D, for attachment to the under side of the table,and a hollow lug, D", extending upward from the part D, and fits snuglyin a holeon theunderside of thetable, and serves as a steady-pin andalso as a part of the socket for the arm-spindle. A hollow hub, d,extends below, forming the balance of the socket for said spindle, andis re-enforced by the rib d. The hub d has a vertical slot, d located bythe side of the rib d, and a lateral slot, d leading from the slot dinto the chamber or socket, and an upwardly-projecting point, d, betweenthe slot d and a depression, (1 on the upper edge of the lug d. Thefront edge of the lug d is re-enforced by an outwardlyprojecting rim,d,that curves upward spirally, forming what might be called a screw-cam.The arm 0 has a spindle, c, integral therewith, that may be passed upfrom below into the socket of the part D when the arm is turned back bythe side of the rib d, in which position of parts the part c of the armwill pass upthrough the slot d and when the arm abuts against the bottomof the flange D the part c of the arm is opposite the lateral slot (Zand the arm may be turned forward over the part d", and the under sideof the part c allowed to rest in the depression (i in which position thearm will extend about parallel with the axis of the table-leaf. Vhen theleaf is raised and the arm turned forward to support it, the part crides on the cam cl, and is elevated thereby, and the relation of partsis such that when the arm is extended to about a right angle to thetable it will engage and support the table-leaf; but until the nearapproach to this point the arm does not come in contact with the leaf,and all rubbing of the parts is thus avoided, and consequently the armmoves freely, and the same free movement of the arm is had when the armis swinging back to lower the table-leaf; also, all wear of the parts istaken up by swinging the arm a trifle farther under the table-leaf, sothat the latter may always be supported in a horizontal position.

The device is simple and can be made at a small initial cost, therebeing but two pieces and no fitting required.

hen the castings have been scoured in a tumbling-box, they are ready foruse.

hen drawers or the frame of the table come too near the end thereof toadmit of using thebroad flange D, this flange is bent down at rightangles, as shown in Fig. 4, and the verticalportion may abut against andbe secured to the said frame of the table.

\Vhat I claim is- 1. In a table-leaf support, the combination, with asupporting device rigidly secured to the table and provided with asocket and a cam, of a laterally-swinging arm adapted to rest on saidcam, and a spindle secured to said arm and resting Within the socket ofthe supporting device, substantially as set forth.

2. In a table-leaf support, the combination, with a laterally-swingingarm and a vertical spindle connected therewith, of a snpportingdevicefor the arm, consisting of a socket for the spindle, a screw-cam forelevating the arm, and the slots d and d substantially as set no forth.

In testimony whereof I sign this specification, in the presence of twoWitnesses, this 17th day of February, 1885.

CHARLES E. MOGLINCHEY.
